SPILE OR TESTNTUBE FOR CASKS OR VATS.

SPECIFICATION forming part of Letters Patent No. 301,354, dated July 1, 1884:.

Application filed April 521, 1884. (No model.)

To a/ZZ whom it may concern:

Be it known that I, FRITZ Gnurzscrr, a citizen ofthe United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Spile or Test- Tubes for Gasks and Vats; and I do hereby declare the following to be a sufficiently full,

` clear, and exact description thereof as to enable others skilled in theart to make and use the said invention.

This invention relates to tubes for `drawing small quantities of 1liquors from vessels for the purpose of testing the condition thereof and observing the progress of fermentation; and it has for its object the facility of drawing small quantities without waste and with the least risk of the tube becoming obstructed by any solid matter floating in the eask, at the same time making the apparatussclf-cleaning, with less cost of material and labor than has been heretofore done.

The nature of this invention consists' in a tapering tube having a screw-thread formed on its surface from the smaller end to within a short distance of the larger end, and made prismatic at its larger end, so as to adapt it to fit a wrench, whereby it may be rotated, and having a tapering bore fitted with a tapering plug extending even with, or projecting slightly beyond, the smaller end of the tube, at which point the plug is fluid-tight in the bore of the tube, and which said plug eX- .iro

tends toward the larger end of the tube into a chamber, where it is provided'with a pro-v jection or project-ions adapted to engage in a notched-key similar to a bayonetclasp,where by the plug can be withdrawn or replaced.

I will now proceed to particularly describe the mode of making and using this invention, referring in so doing to the drawings annexed and the letters of reference marked thereon.

Figure l shows the head or end of a vessel for storing and fermenting beer, with this in. vention applied; Fig. 2, a horizontal View of the tube; Fig. 3, a horizontal view of the plug; Fig. 4L, anend View of the plug; Fig. 5, a horizontal view ofthe key; Fig. G, an end view of the key; Fig. 7, a cross-section of` a made, preferably, of brass, and provided with a screw-thread on the tapering part, marked G, a prismatic head, C2, adapted to fitawrench whereby it may be screwed into the caslchead B. The interior or bore C3 of the tube C is tapering from the smaller end toward the part marked C, where it is chambered out into a cylindric form, into which chamber the exterior of a key-barrel, D', of the key D fits.

In the bore U of the tube C is fitted a plug, E, so as to be fluid-tight therein at the smaller end, and is of such length that the larger end of the plug E is entirely within or covered by the chamber U, when the small end of the plug E is pressed home into the tube C.

On the head of the plug Ii is formed a projection, E', which lits in an angular notch, D2,

in the barrel of the key D, resembling the device known as a bayonetclasp. As shown in Fig. 7, the projection E' is made in duplicate on opposite sides of the head of the plug E, as are also the angular notches D2 in the barrel D' of the key l). This latter form is stronger than that with the single projcction and notch. By means of the key D, engaging the projections E on the plug E in the notch D2, the plug E can be turned in the tube C and withdrawn or replaced; and by reason of lling the entire length ofthe tube C no solid particles can settle and incrust in the tube C, so that upon withdrawing the plug E the fluid that is in the body ofthe eask A immediately flows out for inspection and test, instead of stagnant fluid contained in the channel or tubes of cocks that have hitherto been used for the purpose, and thenecessity here tofore experienced of wasting a considerable amount of liquor before procuring a fair sam! plefroin the body of the eask is avoided.

Having described my invention and the mode of using the saine, what I claim is* A spile or test-tube for casks, consisting of a conical screw-threaded tube provided with for retractng and replacing the plug in the a head or Wrench-seat, whereby it may be tube, substantially as and for the purpose set turned, and a chamber or cavity for the reforth.

with projections adapted to engage in a key, LINN WHEELER.
